Node.js Project to Convert CSV File to JSON File Using csvtojson Library in Javascript

Welcome folks today in this blog post we will be converting csv to json file using csvtojson library in node.js using javascript. All the full source code of the application is shown below.

Get Started

In order to get started you need to install the below library using the below command as shown below

npm i csvtojson

And now we need to make the index.js file and copy paste the following code

index.js

const csvToJson = require('csvtojson');
const fs = require('fs')

1 2	const csvToJson = require('csvtojson'); const fs = require('fs')

As you can see at the very top we are importing the csvtojson module and also we are importing the fs module. And now we need to create the data.csv file and copy paste the same csv code as shown below

csvToJson().fromFile('data.csv').then(jsonObj => {
    // Print the JSON object to the console
    console.log(jsonObj);

    fs.writeFileSync("result.json",JSON.stringify(jsonObj))
});

csvToJson().fromFile('data.csv').then(jsonObj => {

// Print the JSON object to the console

console.log(jsonObj);

fs.writeFileSync("result.json",JSON.stringify(jsonObj))

});

As you can see that we are calling the csvToJson() module and inside it we are calling the fromFile() method to load the input csv file called data.csv and then we are converting the csv file to an array of json objects. And it returns the promise we are handling that using the then statement and inside it we are saving the result as json file using the fs module. We are using the JSON.stringify() method to convert javascript objects to json strings as shown below

Full Source Code

const csvToJson = require('csvtojson');
const fs = require('fs')

csvToJson().fromFile('data.csv').then(jsonObj => {
    // Print the JSON object to the console
    console.log(jsonObj);

    fs.writeFileSync("result.json",JSON.stringify(jsonObj))
});

const csvToJson = require('csvtojson');

const fs = require('fs')

csvToJson().fromFile('data.csv').then(jsonObj => {

// Print the JSON object to the console

console.log(jsonObj);

fs.writeFileSync("result.json",JSON.stringify(jsonObj))

});
